SpletFor low-pass filters, one often preserves mean (i.e. a constant image remains constant after filtering) or energy. For high-pass, some preserves energy, or estimated slope (or higher-order derivatives). Very often, the sum of coefficients of a high-pass filter is zero (a constant signal is zeroe out), thus it cannot be used for normalization.
